"You call yourselves supporters, but as far as I am concerned and as far as Villa are concerned, you will not be welcome at Villa Park for a long time.

"I'm sure neither of you are racists and I'm sure it's very easy to get worked up but behaviour like this can't be tolerated."

Christopher Lester, prosecuting, told how police hid cameras and microphones among fans during Villa's home game with Chelsea on September 2 last year after complaints from supporters about the behaviour of the Blunts at a previous match.

A police-operated camera in the stadium was also trained on them during the game.

Footage shown in court captured the father and son – both wearing Villa shirts – as they barracked Chelsea players and made hand gestures towards the pitch.

Andrew Blunt was seen to shout a string of obscene racist comments at the team's French international Malouda.

He was also recorded telling England international Wright-Phillips: "Go back to your cave."

His father was seen telling the players to "**** off" several times.

Andrew Blunt earlier pleaded guilty to a racially aggravated public order offence and was also ordered to carry out 80 hours of unpaid work and pay £250 costs.

Anthony Blunt admitted a public order offence and must carry out 40 hours of unpaid work and pay £150 costs.
